That is a hard question mainly cause you are trying to compare console to handheld. I think gaming wise this is one of the few times I would give edge to Wii U, but the games between system are somewhat different. Outside of Bayoneta Wii U has more top games that are more of the same with Mario and Zelda franchises. PS Vita tends to have more action/RPG style games. So it will more depend on what you like to play rather than just saying terms of games. In theory you would give edge to Wii U, but if someone has PS4 and PS Vita the games you have on PS4 you can play on your vita....so that is 2 system worth of games....
